Abstract

The use of work facilities that are not ergonomic and do not support work activities during work activities by operators is very at risk of occupational diseases such as Muscosceletal disorders and Repetitive Strain Injury. This disease is an occupational disease that is caused when a person carries out significant work and work activities that affect normal smooth tissue function in the Musculoskeletal system which includes nerves, tendons and muscles. To avoid this, it is necessary to make improvements in terms of work facilities and work methods, namely by scheduling breaks, repairing work facilities is carried out by anthropometric measurements. This measurement is used to obtain specifications for visiting facilities that suit the needs of the operator. To carry out the work improvement method, a work analysis method is needed using the Occupantional Repetitive Action Index (OCRA Index) cost which then results in a work improvement method in the form of removing inefficient work elements and scheduling breaks for operators. The OCRA Index calculations carried out before the repair show that the left hand is in the red-high area with an OCRA Index value of 10.13, which means that the left hand is in a high-risk situation and the right hand is in the red medium area with an OCRA Index value of 7. ,36 which means that the right hand is in a medium-risk state, then improvements are made to the work method which is carried out by eliminating one of the inefficient work elements and scheduling breaks for the operator for 10 minutes so that the operator's working hours are in the first, second working hours , the fourth and sixth are only 50 minutes long. Then the OCRA Index is recalculated after repairs and the left hand is found in the Yellow area with an OCRA Index value of 2.94 which means conditions need to be checked, and the right hand is in the Yellow area. Green with an OCRA Index value of 2.28 which means conditions are acceptable.
